What will be resistance of a bulb rated 100 W – 230 V?
Question
What will be resistance of a bulb rated 100 W – 230 V?
Solution
Sure, to find the resistance of a bulb, we can use Ohm's law, which states that the resistance (R) is equal to the voltage (V) squared divided by the power (P).
Here are the steps:
-
Identify the given values: The power (P) is 100 W and the voltage (V) is 230 V.
-
Substitute the given values into Ohm's law formula: R = V^2 / P
-
Calculate the resistance: R = (230)^2 / 100 = 52900 / 100 = 529 Ohms
So, the resistance of the bulb is 529 Ohms.
